Oh man, this movie has the greatest cast of B-Listers and washed up stars ever:

The Rock, Sarah Michelle Geller, Sean William Scott, Jon Lovitz, Cherri Oteri and half the cast of Upright Citizens Brigade. It also has Justin Timberlake who, about two thirds of the way through, breaks out into a highly choreographed lip-synching of a Killers song for no reason whatsoever.

That scene makes about as much sense as anything else in the movie. It's just a glorious acid trip of a film.
